In this study, a triarylmethine derivative of DMCEBA-BTSA with the high thermal and chemical stability was newly synthesized in order to develop a high-performance image sensor. It showed a high transmittance of more than 80% at 450 nm and △Eab showed a very low color difference of 2.32 after thermal treatment. In solvent resistance, transmittance of 90% was not changed and △Eab showed a low color difference of 0.67 before and after solvent dipping. As a results of the migration test, there was no change at all after dipping in the PGMEA transmittance spectrum. It was confirmed that the newly synthesized blue colorant exhibited excellent thermal and chemical stability and it could be applied to image sensor color filter application as the blue color.As one of the energy storage systems, supercapacitors have quite long charge-discharge cycle life. Among many kinds of electrode materials, metal organic frameworks (MOFs) have unique properties such as high specific surface areas and large pore volume as supercapacitor electrode materials. Nickel-MOFs consist of binary ligand such as 1,3,5-Trimesic acid (H?BTC) and terephthalic acid (TPA) were used as working electrode materials in three electrode cell for capacitor system. When synthesizing MOFs, it is possible to prepare uniform crystals using hydrothermal synthesis. The morphology of composites was analyzed by field emission scanning electron microscopy (FE-SEM). Electrochemical properties were measured by cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) in 6M KOH electrolyte.In this study, we designed and synthesized two blue fluorescence materials using 7,7-dimethyl-9-(10-phenylanthracen-9-yl)-7H-benzo[b]fluoreno[3,4-d]thiophene substituted anthracene derivatives. To characterize their electroluminescent properties, we fabricated the OLED devices using these two emitting materials. Particularly, a device using 7,7-dimethyl-9-(10-phenylanthracen-9-yl)-7Hbenzo[ b]fluoreno[3,4-d]thiophene showed maximum values of luminous efficiency, power efficiency, and external quantum efficiency of 2.42 cd/A, 1.48 lm/W, 3.08% at 20 mA/cm2, respectively with CIE (x, y) coordinates of (0.15, 0.09) at 8.0 V.We fabricated a photodetector device consisting of ITO/NiO x /Perovskite/PC60BM/BCP/Ag. The NiO x layer was deposited using the sol-gel and combustion processes. Combustion-processed NiO x films have advantages such as low annealing temperature, improved perovskite film quality, and better photodetector performance compared to the sol-gel processed NiO x film. The improved film quality, improved charge transfer, and reduced dark current of the device using combustion-processed NiO x film were investigated by measuring the current-voltage characteristics, transient photocurrent, and impedance analysis. The photodetector using the combustion-processed NiO x achieved a high detectivity of 1.20×1013 Jones and bandwidth of over 2 MHz at -0.1 V and 550 nm.New green emitter is designed and synthesized by selecting anthracene having high photoluminescence quantum yield (PLQY) and diphenylamine side group substituted methyl and t-butyl group N9,N10-bis(5-(tert-butyl)-2-methylphenyl)-N9,N10-bis(2,4-dimethylphenyl)anthracene-9,10-diamine (3Me-1Bu-TPADA). https://www.selleckchem.com/products/isa-2011b.html Photophysical, electrochemical, and electroluminescent (EL) properties of 3Me-1Bu-TPADA were investigated. The maximum photoluminescence (PL) emission wavelengths of 3Me-1Bu-TPADA in solution and in a film were 528 nm and 531 nm, respectively. 3Me-1Bu-TPADA has excellent thermal properties with glass transition temperatures (Tg) of 110 °C, melting temperatures (Tm) of 217 °C of, and degradation temperature (Td) of 330 °C. 3Me-1Bu-TPADA was used as an emitting layer in non-doped devices ITO/2-TNATA (60 nm)/NPB (15 nm)/3Me-1Bu-TPADA (30 nm)/Alq? (30 nm)/LiF (1 nm)/Al (200 nm). The 3Me-1Bu-TPADA device showed luminance efficiency of 6.05 cd/A, EQE of 2.68% at 10 mA/cm?.This study prepared silicone hydrogel ophthalmic lenses using 2-hydroxyethylmethacrylate (HEMA), synthesized silicone monomer (SID), dimethylarsinic acid (DMA), N-hydroxyethyl acrylamide (HEA), ethylene glycol dimethacrylate (a crosslinking agent, EGDMA), and azobisisobutyronitrile (an initiator, AIBN). Also, Zirconium oxide (ZrO?), antimony tin oxide (ATO) nanoparticles were added to the silicone hydrogel material to analyze the characteristics of the nanoparticles. The mixture was heated at 130 °C for 2 hours to produce the ophthalmic contact lens by cast mould method. As a result, the manufactured silicone hydrogel lens was prepared having high oxygen permeability and tensile strength while satisfying the basic requirements of ophthalmic hydrogel lens materials. Also, the addition of ZrO? NPs increased tensile strength of the manufactured lens, and ATO NPs were found to improve wettability. Therefore, ZrO? and ATO nanoparticles can be used effectively as additives for functional ophthalmic silicone hydrogel lenses.Pt-supported on amine functionalized MIL-101 (Fe) and nitrogen doped multi-walled carbon nanotube (CNT) composites were synthesized by hydrothermal synthesis and pyrolysis process. Electrochemical properties were measured by cyclic voltammetry (CV), chronoamperometry (CA) and structural analysis was done by field emission scanning electron microscopy (FE-SEM) and Fourier transform infrared spectroscopy (FT-IR). As a result, higher electrochemical surface area (ECSA) and methanol oxidation reactions were obtained, and the electrochemical properties of Pt-c(NH?-MIL-101)@NCNT are better than pristine Pt-c(NH?-MIL-101). The enhanced activity related with the synergy effect from the higher conductivity of N-doped CNT and the better porous nanostructure of carbonized NH?-MIL-101(Fe).Electrochemical redox supercapcitor is one of promising rechargeable power sources for portable electronic, display or telecommunication devices since it has a large energy density, very fast charge/discharge time and long life cycle. In this study, poly(3,4-ethylene dioxythiophene) (PEDOT) thin film as the electrode of electrochemical supercapacitor was deposited on a metal current collector by in-situ polymerization method. Symmetrical electrochemical capacitor was then assembled using PEDOT films as working and counter electrodes, where 0.1 M lithium perchlorate (LiClO?) solution in acetonitrile was used as the electrolyte solution. Typical specific discharge capacitance of the capacitor was about 70 F/g and showed little decrease after 1,000 charge/discharge cycles. We also found that UV irradiation improved the electrochemical properties of redox capacitor by formation of hydrophilic polar groups on PEDOT film surface. After UV irradiation on the surface of PEDOT film for 2 hours with the intensity of 30 mW/cm?, the specific discharge capacitance increased by about 10% compared to capacitance of pristine PEDOT film.
